ChainCatcher news, Blockdaemon has joined the industry's "first" Ethereum (ETH) node operator Risk Standard (NORS) certification release, establishing a new benchmark for the operational security and risk management of Ethereum node operators.In addition, Blockdaemon has now joined the NORS development working group, which "collaborates on the development, iteration, and maintenance of the standard to keep it relevant and accurate." It is reported that the NORS certification simplifies the "due diligence process for banks and large institutions regarding Ethereum staking."

ChainCatcher message, Lido released a disclosure regarding the security incident involving Ethereum node operator Numic. On May 14, Lido DAO contributors became aware of a security vulnerability that affected active node operators using Lido on the Ethereum protocol (Numic).The security vulnerability occurred a few days ago, affecting a developer's machine that had access to the backup of the mainnet validator's cryptographic key materials. It is currently unclear whether the encrypted key materials were accessed, copied, or otherwise manipulated, nor is it known whether the decryption materials for that data were discovered or if the encryption was compromised.In response to the identification that the encrypted backup may have been accessed, and for security reasons, the node operators decided to: set the deposit keys associated with the Lido protocol to zero to avoid receiving any further deposits; and to voluntarily exit all potentially affected keys in a staggered manner over the next few days.As of a few hours ago, all operators' validators have exited (and fully withdrawn). This incident did not affect the operation of the validators, nor did it impact user funds.

ChainCatcher News, the recent "Blockchain White Paper (2023)" released by the China Academy of Information and Communications Technology shows that as of December 2023, Ethereum has approximately 7,500 nodes, with about 3,400 nodes located in the United States and about 1,800 nodes in Germany, accounting for nearly 70% of the total.As of October 2023, the number of global blockchain unicorns (companies valued at over $1 billion) has reached 131, with the top five by valuation being Binance ($45 billion), Upbit ($17 billion), Ripple ($15 billion), Blockchain.com ($14 billion), and OpenSea ($13 billion).

ChainCatcher news, the liquid staking protocol Lido has announced the opening of applications for Ethereum node operators. Applicants must submit their applications by June 26 to be eligible for fast-track evaluation; if fast-track evaluation is not needed, applications will remain open until July 14 at 7:59 AM Beijing time.In February of this year, Lido launched the Staking Router feature, which is a new modular architecture designed to allow anyone (including independent stakers) to become a node operator while providing stakers with an easy staking/unstaking experience.

链捕手消息，托管约 10% 以太坊节点的云服务提供商 Hetzner 官方社交账号在回复加密节点许可问题时表示，不允许将 Hetzner 产品用于任何与采矿相关的应用，即使是远程相关的应用，包括以太坊。Hetzner 表示，知悉目前有很多以太坊用户，一直在内部讨论如何以最好的方式解决这个问题。（来源链接）

链捕手消息，据 Cointelegraph 报道，三大云提供商占据了以太坊主网上 69% 的托管节点，其中超过 50% 来自亚马逊网络服务 (AWS)，超过 15% 来自 Hetzner，4.1% 来自 OVH。这可能“将以太坊暴露于中心故障点”。 此外，Ethernode 数据还显示，节点在地理上最集中在美国（46.4%）和德国（13.4%），占全球分布式以太坊节点的近 60%。（Cointelegraph）

链捕手消息，据雅虎财经报道，SpaceX将于7月3日向国际空间站（ISS）发射一个以太坊（ETH）节点，为首次将以太坊节点送入太空。在最近的一份新闻稿中，SpaceChain透露，他们已与SpaceX签约，将通过猎鹰9号火箭将节点送至国际空间站。据悉，该以太坊节点将是SpaceChain 第四个进入太空的区块链有效载荷，将由SpaceChain的客户Nexus Inc安装。此外，SpaceX还将在2021年6月24日使用其猎鹰9号火箭再次前往国际空间站，届时它将携带为Biteeu、Divine和Nexus Inc.创建的三个节点。 SpaceChain就此次发射表示："这将是SpaceChain的区块链有效载荷在太空的第四次发射，也是在国际空间站上首次展示将以太坊技术融入其硬件。这次任务的实现要感谢Nanoracks及其与美国国家航空航天局的空间法协议。"（来源链接）
